Mobile Dust Collector Case Studies


City Rail Link Project

City Rail Link (CRL) is Auckland’s first underground rail line and the largest transport infrastructure project ever undertaken in New Zealand. CRL will transform the downtown Britomart Transport Centre into a two-way through-station, doubling the capacity, reducing travel times and supporting a growing population with a world-class transit system.


Ventilation Design Systems in Tunnelling

Ventilation Design Systems in Tunnelling Three Key Ventilation Design Systems The Importance of Ventilation and Dust Control A critical aspect of any tunnel construction is ventilation design and dust control, so that workers exposure to fumes and dust are reduced to safe, acceptable levels. Silica or silicon dioxide is a naturally occurring and widely abundant mineral that forms a major component of most rocks and soils. Crystalline silica dust is the biggest risk to construction worke [...]


Melbourne Metro Tunnel Project

The Metro Tunnel provided some unique challenges for the ventilation design, including space and noise constraints plus the location on excavation works within the CBD. The design was created using Ventsim Design 5 to simulate ventilation, airflows, pressures, heat, gases, radon, fire and other key ventilation data to be considered, along with managing the financial constraints of the project.

Fixed Unit Dust Collector Case Studies


Crushing Plant Dust Extraction System

Our clients’ site expansion works, included a tender for a dust extraction system to manage dust created by two secondary and tertiary cone crushers and three screening plants. Grydale were awarded the contract to design, manufacture and install a Grydale JMS 48 F-Series Dust Extraction System. This unit provided 38,000m3/hr of air flow at -2.0kPA, which offered the capacity to extract dust from the two secondary and tertiary cone crushers and three screening plants.
